Abstract
This disclosure provides a system and method for generating an ultrasound image. The method includes receiving a raw ultrasound signal output from an ultrasound device and performing operations to transform the raw ultrasound signal into an enhanced ultrasound image. The enhanced ultrasound image may be further processed by radial symmetry filtering to generate a radial symmetry image. Both the enhanced image and the radial symmetry image can be by a medical practitioner to make a liver or kidney cancer diagnosis exclusively based on ultrasound data.
Claims20
A system for generating a liver ultrasound image, comprising:
- a non-transitory, computer readable memory;
- one or more processors;
- and
- a computer-readable medium containing programming instructions that, when executed by the one or more processors, cause the system to:
- acquire a raw liver ultrasound signal output from an ultrasound device;
- generate filtered liver ultrasound image data by filtering the raw liver ultrasound signal to transform information from a signal domain to a frequency domain;
- extract image phase and energy features from the filtered liver ultrasound image data by an alpha scale filtering that is configured to extract the image phase features;
- generate a filtered liver ultrasound signal by transforming the image phase and energy features from the frequency domain to the signal domain;
- produce a transmission map estimation based on a backscattered liver ultrasound signal from a tissue interface;
- and
- enhance the image phase and energy features of the filtered liver ultrasound signal based on the transmission map estimation so that portions of a soft liver tissue associated therewith are made darker or lighter in an enhanced liver ultrasound image.
